PRODUCT OVERVIEW
Single Output UCH Models
Isolated, “Half-Brick”
1.8?15V Output DC/DC Converters
NOT RECOMMENDED
FOR NEW DESIGNS

The high ef f? ciency, low noise and long-term reli-
ability that de ?nes Murata Power Solutions’ DC/
DC Converters now comes to you in the standard
“half-brick con ? guration (2.3 ? x 2.4? x 0.40?).
Our new UCH Series is certi i? ed to UL/EN60950-
1 safety requirements (some models pending),
including each European country ’s deviations. All
models have BASIC insulation; guarantee 2250Vdc
(in to out) isolation; and because they are designed
impressive ef?ciencies. Output voltages are
1.8?to?15 Volts. The input voltage range is 36 to 75
or 18 to 36 Volts. All models meet the Low Voltage
Directive (LVD).
For high reliability and affordability, Murata
Power Solutions utilizes high-speed automatic
assembly to construct the UCH’s proven SMT-
on-pcb designs. An optional baseplate offers full
output power at maximum temperature.
FEATURES
?? Standard “half-brick” con?guration
?? Certi ?ed to UL-60950-1, CSA-C22.2 No.

Full
?? Fully isolated, 2250Vdc guaranteed
?? Output voltages: 1.8 – 15 Volts
?? range: 36-75V or 18-36V
?? 50-150 Watt output power
?? Reliable SMT-on-pcb construction
? Input under and output overvoltage shutdown
?? Output current limiting and short-circuit
protection
?? On/off, V OUT trim and sense functions
?? Modi?cations and customs for OEMs
with Class B thermal insulation, satisfy all safety
requirements over their full operating tempera-
tures. Construction/attach meets stringent RoHS-6
speci?cations.
UCH Models are designed for demanding tele-
com, datacom and networking applications. Their
“semi-synchronous-recti?er” design achieves
UCH’s feature input ?lters, input undervoltage
and overvoltage lockout, output current limiting,
short-circuit protection, and thermal shutdown.
Additionally, all devices have output trim capability
and an on/off control pin that can be ordered with
either logic type.
